A technique developed from the Nara clan's hidenShadow Imitation Technique with combat in mind. It is possible to inflict direct damage to the enemy by transforming and moving shadows endowed with physical power.

It is possible to attack body parts like fingers and such by turning the shadow slender and to bind the opponent's body in order to restrain them. It was given its name because, above all else, strangulation is the most efficient method. The smaller the distance to the target, the greater the power of the shadow. This technique cannot be used for an extended period of time, as it weakens with each passing minute.

Trivia

Shikamaru used this technique on himself to break his finger, using the pain to escape from Tayuya's genjutsu.

The technique appears in Naruto: Ultimate Ninja Storm as Shikamaru's ultimate technique. However, rather than strangling the opponent, it binds them to a nearby rock and then squeezes them, destroying the rock and crushing the opponent.
